Mask Coupling Apparatus with Elastic Strap Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mask-to-helmet coupling systems require removing the helmet to adjust straps, making adjustments difficult and time-consuming, especially in field conditions, and often cause discomfort due to pressure points and headaches.
Innovation Solution
A mask coupling apparatus featuring adjustable elastic straps with quick-release assemblies and mounting rails on the helmet, allowing for easy coupling and uncoupling, and independent adjustment of strap lengths for improved fit and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional sliding tab adjusting mechanisms are used on mask straps, then the mask can be adjusted to fit different head sizes, but the adjustment process becomes difficult and time-consuming, especially when wearing gloves
Solution Approach 1:
The mask strap system is divided into multiple discrete adjustment points along the strap, allowing the user to select and adjust individual segments rather than manipulating a continuous sliding mechanism. This segmentation makes the adjustment process simpler and more accessible, especially when wearing gloves.
Solution Approach 2:
A card or tag with corresponding holes is introduced as an intermediary tool to facilitate adjustment. The user inserts the card through the strap and coupling to secure the desired length, making the adjustment process easier and more precise without requiring complex manual manipulation of the strap itself.
2Adaptability or versatility
If traditional sliding tab mechanisms are used for mask strap adjustment, then the mask can be adjusted while worn, but the mechanism causes discomfort such as pressure points and headaches
Solution Approach 1:
The problematic sliding tab mechanism that causes pressure points and headaches is completely removed from the system. Instead, the patent uses a card insertion system that distributes pressure more evenly across the head and eliminates the concentrated pressure points caused by traditional sliding tabs.
Solution Approach 2:
The adjustment mechanism changes from a sliding tab system to a discrete hole-and-card system, fundamentally altering how the strap secures to the head. This parameter change in the adjustment mechanism eliminates the harmful pressure points while maintaining the ability to adjust mask fit.
3Reliability
If helmet is worn over mask straps traditionally, then the mask and helmet can both be worn securely, but the helmet must be removed to adjust the mask straps
Solution Approach 1:
The mask strap adjustment points are pre-positioned and designed to be accessible over the helmet, allowing users to make adjustments without removing the helmet. The coupling mechanism is specifically designed to accommodate helmet wear while maintaining adjustment capability.
4Productivity
If quick-release assemblies are used on mask connectors, then the mask can be quickly coupled and uncoupled from the helmet, but the connecting mechanism becomes more complex
Solution Approach 1:
The quick-release connector is designed to be operated by a single simple motion - pushing a release tab that automatically disengages the coupling. This self-service design achieves quick release functionality without requiring complex multi-step mechanisms or tools.
